| titleOfInvention | Process for the preparation of olefins from ethanol |
| abstract | The present invention relates to a process for the conversion of ethanol essentially to produce ethylene and propylene, comprising the following steps: a) introducing a stream comprising ethanol, optionally water, optionally inert components, under a partial pressure of at least about 0.2 MPa into reactor A (also referred to as a first low temperature reaction zone); b) contacting said stream with said catalyst (A1) in said reactor (A) under conditions effective to convert at least some ethanol into essentially ethylene, propylene and olefins having at least 4 carbon atoms (C4 + olefins); c) recovering the effluent from the reactor comprising: C4 + fractions mainly containing ethylene and olefins having at least 4 carbon atoms (C4 + olefins), Propylene and various hydrocarbons, Water of step a), optionally unconverted ethanol and any inactive components; d) fractionating the effluent of step c) to remove water, unconverted ethanol, optionally inert components, optionally propylene and optionally all or some of various hydrocarbons, thereby essentially ethylene, olefins having at least 4 carbon atoms (C4 + olefins) And optionally obtaining stream (D) comprising the inert component; e) at least part of said stream (D) optionally mixed with stream (D1) comprising at least 4 olefins (C4 + olefins) having said mixture (D) + (D1) comprising at least 10% by weight of C4 + olefins Introducing into an OCP reactor (also referred to as a second high temperature reaction zone); f) contacting said stream comprising at least some (D) and any of (D1) in said OCP reactor with a catalyst selective for light olefins in the effluent to produce an effluent having an olefin content of lower molecular weight than the feedstock. ; g) fractionating the effluent of step f) to produce a fraction consisting of at least an ethylene stream, a propylene stream and essentially hydrocarbons having at least 4 carbon atoms, Optionally, all or part of the ethylene at the inlet of the OCP reactor of step f) or at the inlet of reactor (A), or some at the inlet of the OCP reactor of step f) and some ethylene at the inlet of reactor (A) Recycling step, Optionally, recycling the fraction consisting essentially of hydrocarbons having at least 4 carbon atoms at the inlet of the OCP reactor. |
